Mechanical Commissioning Technician

X.ai

Southaven, MS, USA

SpaceXAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

About The Role

We are seeking a highly skilled Mechanical Commissioning Technician to support the buildout and startup of SpaceXAI's high-performance data centers. In this critical hands-on role, you will perform commissioning, testing, and troubleshooting of mechanical systems that cool and support our next-generation AI supercomputing infrastructure.

This is a full-time, onsite role with significant travel to SpaceXAI data center sites.

Responsibilities

• Execute mechanical commissioning activities for chilled water, condenser water, cooling towers, pumps, heat exchangers, air handlers, computer-room cooling, liquid-cooling equipment, and associated controls in data center environments.
• Perform flush, fill, leak, and pressure tests; verify valve lineup, flow, temperature, and pressure against design and sequence of operations.
• Complete point-to-point checks with controls technicians and confirm sensors, actuators, interlocks, and alarms respond correctly.
• Troubleshoot and resolve mechanical issues during pre-commissioning, commissioning, and startup phases.
• Develop and execute detailed commissioning test procedures, scripts, and documentation in accordance with project specifications and industry standards.
• Collaborate with EPC contractors, OEM vendors, and SpaceXAI engineers to coordinate startup sequences and integrated system testing.
• Walk systems against drawings, mark redlines, write punch-list items, and drive closeout until deficiencies are cleared.
• Ensure strict adherence to safety protocols, LOTO procedures, and quality standards during all commissioning activities.
• Maintain accurate as-built documentation, test records, and commissioning reports.
• Support training of operations and maintenance teams on commissioned mechanical systems.
• Participate in constructability reviews and provide field feedback to improve design and installation quality.

Basic Qualifications

• 3+ years of hands-on mechanical, HVAC, pipefitting, or commissioning experience in data centers, power plants, or large industrial facilities.
• Strong working knowledge of chilled-water plants, pumping systems, heat transfer equipment, and related mechanical distribution.
• Experience with commissioning and field test equipment (pressure gauges, flow meters, temperature instruments, leak-detection tools, etc.).
• Ability to read and interpret piping and instrumentation diagrams, mechanical drawings, and equipment submittals.
• Strong safety mindset with current OSHA 10/30 or equivalent training.
• Willingness to work extended hours, nights, and weekends during critical commissioning windows.

Preferred Skills And Experience

• Prior commissioning experience on hyperscale data center projects or mission-critical facilities.
• Experience with liquid-cooling distribution, cooling towers, and primary/secondary pumping.
• Familiarity with building management or industrial control sequences.
• EPA Section 608 refrigerant certification.
• Technical degree or trade school certification in Mechanical Engineering Technology, HVAC, or a related field.
• Proficiency with commissioning management software (e.g., CxPro, Procore, or similar).

Additional Requirements

• Ability to travel extensively to SpaceXAI construction sites and remain onsite during peak commissioning phases.
• Capability to work in industrial environments, climb ladders, lift moderate loads, and wear PPE for extended periods.
